I believe it's more urgent to get rid of "serving" as measurement.I recently tried to build up a dash diet shopping list and was sent on a wild hunt for what is a serving exactly (turns out a serving is different depending on the food and measured in different cups and other imperial units).
Most dash diet books (or others) I read spend 200 pages out of 250 explaining basic useless nutrition factoids then get on a "sample week menus" that aren't practical at all if all you want to know is "how much pounds of this and that should I eat per day or per week ?".
I should open a blog about how to get that (easy recipes, easy shopping list), would be a nice journey.
